NEW YORK, March 11 (Reuters) - U.S. stock index futures
pointed to a slightly higher open on Wednesday, implying a
modest rebound from a sharp decline in the previous session,
though questions remain about when the Federal Reserve would
adjust its rate policies.

Wall Street fell sharply on Tuesday, with the S&P 500
suffering its biggest one-day decline in two months, surpassing
a selloff of similar magnitude on Friday. The benchmark index is
down about 2.7 percent over the past three sessions, while the
CBOE Volatility index, a measure of investor anxiety, is
up almost 19 percent over that period.

The weakness has come on the increasing view the Fed may
raise interest rates as soon as June. Those worries pushed the
U.S. dollar to a nearly 12-year peak against the euro on
Tuesday, and added to concerns the dollar will continue to weigh
on U.S. multinationals' earnings.

The U.S. dollar index stayed strong on Wednesday, up
0.7 percent. The index has risen in five of the past six
sessions, up more than 4 percent over that period. The euro
fell 1 percent and hit a 12-year low.
